WIN7 64bit ASUS P8Z68-V PRO/GEN3. I have a SSD on SATA1 with the OS,
HDD on SATA2 with music files and a DVD drive on SATA6. Everything was
fine until I updated my BIOS. Now although everything works OK and the
OS sees all [computer management, device manager etc.] the BIOS only
'sees' the DVD drive and shows SAT1 & SAT2 as not installed, empty.
I tried installing an older BIOS and the same occurs. It would not
accept the original BIOS as it said it was too old.
What could be causing this?

Thanks for your help. I removed the CMOS battery and shorted the pins. I
then replaced the SSD and HDD with another HDD. The BIOS still doesn't
'see' any SATA drives apart from the DVD.
In the manual, I see these SATA ports on the motherboard.
Which ports are you testing at the moment ?
I would "fill from the bottom up", to establish that something is working.
The 9172 ports, may have a separate screen or something (not treated the
same as Z68 ports, as 9172 is outside of the chipset).
9172 Ports (2)
Z68 SATA III (2)
Z68 SATA II (2)
Z68 SATA II (2)
Now, while in the BIOS, take a look at section 3.5.4 of the manual.
(I'm looking at the downloadable E6850 version of the PDF manual.)
That's the manual section that covers the SATA Config BIOS page.
There's not much to it - it shows the status of the six Z68 ports
and whether something is detected or not.
If a device is definitely connected, the port is enabled, and
yet nothing is "Detected", then:
1) Check that storage device is receiving power. Use the power
connector off the working DVD drive, if necessary. Listen
for sound of spinning media, on mechanical hard drives.
2) Check any voltage regulator adjustments in the BIOS, that
affect Z68. The "PCH Voltage" is probably a core supply for
Z68 (Southbridge,SATA ports). The VCCIO, I'm not sure what that's
for, as the terminology is rather ambiguous. Could it affect
Z68 SATA launch voltage ? Who knows.
Some of those regulators now, they're extremely accurate, and
not the crappy stuff they used to use. So there's really fewer
excuses for the voltage to not be absolutely correct. While I
did have to adjust one of those voltages on my current
motherboard, it wasn't something affecting SATA ports
at all. (Mine was a RAM stability problem, and needed
Vnb to be cranked up a notch.)
That's about all the user adjustable stuff I can think of.
A number of years ago, mis-adjusting a PCI Express clock frequency,
could knock out SATA ports (because at one time, some of the
clock signals were shared). It was only done that way, for a
generation of boards, until they added a few more clock domains
to the designs. That sort of thing shouldn't happen now.
HTH,
